From cd0511503532320e68396c90617d5f91ed7cae1c Mon Sep 17 00:00:00 2001 From: Teppei Kamijou Date: Wed, 12 Dec 2012 15:38:05 +0100 Subject: [PATCH] mmc: sh_mmcif: force to fail CMD52 immediately mmc_rescan() sends CMD52 (SD_IO_RW_DIRECT) to reset SDIO card during card detection. CMD52 should be ignored by SD/eMMC cards, but we can also abort it in the driver immediately, since MMCIF doesn't support SDIO cards anyway.
